Fire Retardant

Technical Specifications for Tripolymer Foam Insultation: Tripolymer products are phenol-based synthetic polymers. Tripolymer can be installed in any cavity through 1” - 2” holes or sprayed into new stud construction. Initial set takes approximately 10 - 30 seconds. Final curing is within 48 to 72 hours, depending upon thickness. Tripolymer is a cold-setting process, independent of ambient temperatures. There is no further expansion once the foam leaves the delivery-hose. Tripolymer does not contain or emit CFC’s.

A 30# crib fuel cource was constructed of 1 1/2” x 1 1/2” sticks of white fir cut to 15” lengths. The cribdry wood has a weight of approximately 30# and had a 15” square dimension. One eight-penny nail at each intersection of two sticks held the formation together. The crib was pre-conditioned to a maximum 8% moisture content before testing. The crib was elevated a minimum of 3” from the floor by four corner brick pieces 4” square. One pound of fluffed wood excelsior is distributed around the bricks with the excelsior extending from the wall surfaces and covering an area approximately 21” square. The excelisor is soaked with 4 ounces of absolute ethyl alcohol just prior to ignition.

The test, conducted on the Phenofoam panels exposed to the interior of the fire test room, was monitored by both continous video and polaroid pictures at 2 minute intervals. The test indicated that the combustion of the Phenofoam panel did not extend to the outer extremeties of the test area within a 15 minute period after ignition of the excelsior.

Report on Ignition Properties of Plastic, Report #IP84-132, dated July 5, 1984, was prepared by United States Testing Company, Inc. The tests conducted in accordance with the test starndard for the Ignition Properties of Plastics, ASTM D-1929 concluded in the following properties of the Phenofoam:

Minimum flash-ignition temperature930 degrees F
Minimum self-ignition temperature1080 degrees F
